In a food chain, energy is passed through one link to another. When a herbivore eats only a certain fraction of the energy, (which comes from the food) it becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore in order to carry out its life processes (ex. movement, digestion, reproduction). It doesn’t necessarily threaten the plants survival, there’s also a benefit. When a animals poops out the fruit (defecate) in another area those seeds get carried to new places with the help of a dab of fertilizer and a little bit of moisture. They also help supply nutrients when they die and decompose.

Answer:
1) The solubility product of the lead(II) chloride is .
2) The solubility of the aluminium hydroxide is .
3)The given statement is false.
Explanation:
1)
Solubility of lead chloride =
S 2S
The solubility product of the lead(II) chloride =
The solubility product of the lead(II) chloride is .
2)
Concentration of aluminium nitrate = 0.000010 M
Concentration of aluminum ion =
Solubility of aluminium hydroxide in aluminum nitrate solution =
S 3S
The solubility product of the aluminium nitrate =
The solubility of the aluminium hydroxide is .
3.
Mass of NaCl= 3.5 mg = 0.0035 g
1 mg = 0.001 g
Moles of NaCl =
Volume of the solution = 0.250 L
1 mole of NaCl gives 1 mole of sodium ion and 1 mole of chloride ions.
Moles of lead (II) nitrate = n
Volume of the solution = 0.250 L
Molarity lead(II) nitrate = 0.12 M
1 mole of lead nitrate gives 1 mole of lead (II) ion and 2 moles of nitrate ions.
Solubility of lead(II) chloride =
Ionic product of the lead chloride in solution :
( no precipitation)
The given statement is false.
